RQ4077 raced @ 1.042 in Hobart.Thanks but I was after any information as to the rumour that it was recently forced to be remeasured for IRC as the rating in the Nationals was suspicious. There's a Tassie boat which would have won otherwise.
RQ4077 IRC appears in this years IRC list (14th December 2020) @ 1.045
Both ratings are pretty low for a 40.7 anyway.
Increase could be a number of factors - this season with more sail area, bling ..... or measurement correction. Usually would expect if nothing changes for IRC to tick down with age credit.
